Answer 2

Answer:

AOC=36, BOD=54 and AOE= 108.

Step-by-step explanation:

Since AOB is a straight line, we have

∠AOE+∠BOE=180

o

=3x + 72

=180.

⇒3x =108

⇒x=36

We also know that

∴∠AOC+∠COD+∠BOD=180 (∵ straight angle)

⇒x +90 +y

=180

⇒36 +90 +y

=180y

=180 −126

=54

∴∠AOC=36 ,∠BOD=54 and ∠AOE=108
